Filed: 1973-11-08
Abstract: 1446464 Thermal-rock cutting HUMPHREYS CORP 8 Nov 1973 51824/73 Heading E1F [Also in Division H5] A method of cutting rock 12 involves the use of a plasma torch 20 to direct a plasma stream 86 against the rock and supplying through the plasma stream electrical power to further heat the rock. In one preferred embodiment the impinging of the plasma stream on the rock creates on the rock a molten film and in this film flowing electrical current both further heats the film and the rock underlying the film to form a cut in the rock. Preferably the plasma stream has a velocity of at least 3000 ft/sec, an additive may be supplied via the plasma stream to the molten rock to modify the characteristics thereof, and spalling of the heated rock may be enhanced by directing a jet of coolant fluid against the rock. In the other preferred embodiment dielectric heating and thermal stressing of the rock between two cuts is caused by applying an A.C. voltage of a suitable frequency across the plasma streams of two plasma torches, the streams providing the necessary electrical contact between the electrical supply and rock at the bottoms of the cuts. Preferably the voltage gradient is in the range of 750-7500 volts/inch and the velocity of each plasma stream is in excess of 20 ft./sec. The two procedures may be applied sequentially to the rock. U.S. Specification 3214623 is referred to.

Within the housing 2 is fixed a cup-shaped spring housing 12 with disc springs 17, the housing 12 also locating pressure rings 14, 15 with a plurality of compression springs 16 therebetween. The ring 14 engages a thrust bearing 13 which abuts a shoulder on the spindle 7. At the opposite end of the housing 2 there is provided a switch 19 on a support 21 which is adjustable by way of threaded means 24 a calibrated dial 22, 23 permitting the adjustment to be indicated in force units. In operation a workpiece (not shown) is engaged with the centre 4 and the motor 11 started to rotate the spindle 7 which causes axial displacement of the sleeve 3 with the centre 4 until rigid engagement between the centre and workpiece occurs. This stops the displacement of the sleeve and causes axial displacement of the spindle 7 against the pressure of the springs 16 and 17. The spindle displacement continues until the conical end 28 of the spindle actuates the prepositioned switch 19 which stops the motor 11 and which maintains a predetermined axial force by the springs between the centre and workpiece which is indicated by the dial 23. The two spring systems shown permit an initial and a main force to be exerted by the centre on the workpiece.

Abstract: 1380289 Setting electric clocks SEIKO KOKI KK 16 Nov 1972 [19 Nov 1971] 52975/72 Heading G3T  In a timepiece driven by an electric motor and having a plurality of time indicators e.g. digit wheels, in order to permit accurate setting of the indicator of the smallest time units e.g. a seconds wheel, there is provided a manually operable means for preventing further advance of said time indicator after it has reached a predetermined position, e.g. zero seconds, and means for interrupting the drive to the indicator at this time. As shown, seconds wheel 1 is attached to a gear 2 which is normally driven by a pinion 4 and carries a projection 7. A lever 8 is pivoted at 10 and normally biased by a spring 12 against a stop 11 but may be manually rotated so that a catch 9 thereon enters the path of projection 7 to stop the wheel I at zero seconds indication. The synchronous driving motor can continue to rotate as shaft 5 of the pinion 4 can slip in slot 6 against a bias spring (not shown). The drive to the wheel 1 may alternatively be interrupted by a friction clutch which is mechanically or electrically controlled by the displacement of the shaft 5, or the displacement may open a switch in the motor circuit. Such a switch may also be controlled by the catch 9 Fig. 3 (not shown).

[Also in Division H2] A first magnetic member 10 has a coil 14 and a plurality of low reluctance regions such that when the coil is energized a plurality of regions are magnetized on the edge 20 of a second magnetic member 8. When member 8 is moved relative to member 10, a pulse is induced in coil 14 each time the magnetized regions on member 8 are aligned with the low reluctance regions on member 10. The device may be used to produce timing signals for information sensed from a moving record card, coil 14 being energized to record the magnetic pattern when a photo-cell is uncovered by the leading edge of the card and the first column of the card is spaced by the width of one column from the sensing elements, the pulses subsequently induced in coil 14 occurring at one-column intervals. If the lowreluctance regions of member 10 extend over only half the circumference, as member 8 rotates, the pulses induced in coil 14 will steadily decrease in amplitude by increments to zero and then increase again as member 8 performs one revolution. If every third lowreluctance region is omitted, every third pulse in coil 14 will be of greater amplitude.

Title: Electron multipliers

Filed: 1971-11-17
Abstract: 1401969 Electron multipliers MULLARD Ltd 2 Oct 1972 [17 Nov 1971] 53371/71 Heading H1D An electron multiplier channel plate is formed as a laminated structure of alternate conductor layers M and resistive separator layers D, with aligned apertures providing the channels, whereby charge build-up on the layers D is prevented. The conductor layers may be of steel plate, with the walls of the apertures coated with secondary emissive material, and the separator layers of a lead oxide containing glass which has been heated, in hydrogen, after fabrication, to provide a resistive surface lead layer, or of vitreous carbon. Alternatively, the conductor layers may be of aluminium, and the separator layers of aluminium oxide coated with a resistive layer. In low current applications, the resistive layers may be exposed to the electron trajectories, such that they supply a portion of the secondary emission, and the current flowing through the resistive layers may be employed to maintain the potentials of the successive conductive plates, dispersing with the use of an external resistor chain. For high current applications, e.g. when the channel plate is scanned by a cathode ray beam, the construction is arranged such that the resistive layers are substantially concealed from the electron trajectories. Methods of fabrication discussed include: coating apertured steel conductor plates on one side with glass, etching the glass through the plate apertures, and heating a stack of the plates until the glass melts and bonds them together; and a variety of methods involving the combined use of photo and etch resists, e.g. anodizing one surface of an aluminium plate, coating the anodized layer and the other surface of the aluminium layer with a photo-resist and an etch resist, respectively, exposing the photo-resist to a dot pattern, etching through the alumina and aluminium layers, removing the resists, and applying a resistive coating to the exposed channel surfaces of the alumina. If maximum concealment of the resistive material D from the electron trajectories is required, it may be etched back still further subsequent to the assembly and bonding together of a stack of plates, Fig. 8. Successive plates of a stack may be staggered, to give curved or slanting channels (Figs. 9 and 10, not shown); an electron-permeable conductive membrane, or a photo-emissive layer, may be provided at the channel entrances; and square section channels may be employed.
